Chapter 2 Simulation Examples Banks, Carson, Nelson & Nicol Discrete-Event System Simulation ٢ Simulation steps using Simulation Table Determine the characteristics of each of the inputs to the simulation (probability distributions). Construct a simulation table (repetition 1). For each repetition i , generate a value for the inputs, and evaluate function, calculating a value of response y i .
